Press all along the edge of the tape with your spudger to stick it securely to the MacBook Pro's aluminum case, sealing off the speaker from the battery.

Be careful not to poke or puncture the battery.

Fold the tape over and lightly adhere it to the speaker to keep it out of the way.

The foam bumpers on top of the speaker may tear when peeling the tape off. Don't press the tape directly onto the bumpers.
